Hi Jérémy,

I also get the same error as Pierre, and I copied your file precisely, on a recent guix. I don't think specifying a URL will help, but specifying a hash definetely does. To get a valid hash (but not necessarily the one you are looking for), you can use "guix hash <some-file>". This allows the baild process to start here, although it fails to download anything apart from build-system packages, of course.
